| Transportation rates are vital components in the structure of U.S. grain exports. In this paper we study the dynamic properties of corn and soybean prices, and barge, rail and ocean shipping rates using time series analysis on monthly 1992-2001 data. Using Error Correction Model and Directed Acyclic Graphs, we capture the interconnectivity between the transportation rates and grain prices at selected domestic and export markets. We find Illinois processor prices are important sources of price discovery for both corn and soybeans. Further, barge rates explain about 2-4% of the variation in grain prices while rail rates explain about 10-12% of the variation in corn and soybean prices. |

| Directed Acyclic Graphs (DAG's) and Error Correction Models (ECM's) are employed to analyze questions of price discovery between spatially separated commodity markets and the transportation market linking them together. Results from our analysis suggest that these markets are highly interconnected but that it is the inland commodity market that is strongly influenced by both the transportation and commodity export markets in contemporaneous time. However, the commodity markets affect the volatility of the transportation market over longer horizons. Our results suggest that transportation rates are critical in the price discovery process lending support for the recent development of exchange traded barge rate futures contracts. |

| This research investigates various unresolved issues regarding futures markets, using formal methods appropriate for inferring causal relationships from observational data when some relevant quantities are hidden. We find no evidence supporting the generalized version of Keynes's theory of normal backwardation. We find no evidence supporting theories that predict that the level of activity of speculators or uninformed traders affects the level of price volatility, either positively or negatively. Our evidence strongly supports the mixture of distribution hypothesis (MDH) that trading volume and price volatility have one or more latent common causes, resulting in their positive correlation. |

| Using quarterly U.S. census division data for time period 1975-2006, this paper investigates the dynamic relationships among the house prices of nine divisions (regions): Pacific, Mountain, South Atlantic, Middle Atlantic, New England, East South Central, West South Central, West North Central, and East North Central. Johansen’s ML procedure is applied to shed light on the short-run and long-run components on the error correction model. Furthermore, a symmetric error-correction model is estimated followed by the contemporaneous causality structure that is provided by the directed acyclic graphs. The latter is used as an “input” for estimating the impulse response functions along with the forecast error variance decompositions. The results provide evidence... |

| Because of the recent soaring petroleum price and growing environmental concerns, biodiesel has become an important alternative fuel. Biodiesel is the mono alky esters made from a vegetable oil, such as soybean or rapeseed oil, or sometimes from animal fats. The escalation in world petroleum price has stimulated the demand for biodiesel, which consequently expanded the use of vegetable oils. This paper investigates the long-run interdependence between major edible oil prices and examines the dynamic relationship between vegetable and crude oil prices. The data consists of 378 weekly observations extending from the first week of January in 1999 to the fourth week of March in 2006. We apply time-series analytical mechanisms and directed acyclic graphs... |

| Economic theory is replete with causal hypotheses that are scarcely tested because economists are generally constrained to work with observational data. This article describes the use of causal inference methods for testing a hypothesis that one random variable causes another. Contingent on a sufficiently strong correspondence between the hypothesized cause and effect, an appropriately related third variable can be employed for such a test. The procedure is intuitive, and is easy to implement. The basic logic of the procedure naturally suggests strong and weak grounds for rejecting the hypothesized causal relationship. Monte Carlo results suggest that weakly-grounded rejections are unreliable for small samples, but reasonably reliable for large... |

| Vector autoregression was utilized to investigate dynamic relationships existing between prices of purebred bulls and prices of slaughter steers, utility cows, feeder calves, and cow-calf pairs. Results suggest purebred bull prices respond most quickly to an increase in utility cow prices (proxy for slaughter bull prices). Feeder calf prices exhibited the most pronounced positive effect on the price of herd sires, with a lagged response which took over two years to build. |

| Using advanced methods of directed acyclic graphs with Bernanke structural vector autoregression models, this article extends recent econometric research on quarterly U.S. markets for wheat and wheat-based value-added products downstream. Analyses of impulse response simulations and forecast error variance decompositions provide updated estimates of market elasticity parameters that drive these markets, and updated policy-relevant information on how these quarterly markets run and dynamically interact. Results suggest that movements in wheat and downstream wheat-based markets strongly influence each other, although most of these effects occur at the longer-run horizons beyond a single crop cycle. |

| The Staggers Rail Act of 1980 granted railroads freedom to establish rates and enter into confidential contracts with grain shippers. Recent legislation (1986) required that certain contract terms be disclosed. This study shows rail rates in the Plains region commenced an upward trend after implementation of the disclosure policy. Results suggest contract disclosure and increased reliance on posted tariffs facilitated rate coordination within the oligopolistic railroad industry. |

| Statistical methods are used to study relationships between research expenditures (adjusted for inflation) made from producer checkoff programs and soybean yields and net revenues in the United States for the years 1978 – 2007. Results presented are for yield and net revenue data and research expenditures for the entire United States. We find that research expenditures over the years 1994 to 2007 are responsible for a 0.95 bushel per acre per year increase in soybean yields. We calculate net producer revenues to be about $17 per acre higher than would have been the case without the soybean research checkoff expenditures. |

| Temporal relationships are investigated among fabricated cut prices, carcass value, and fed cattle prices. Also, linkages between fed cattle and wholesale beef prices are examined using vector autoregressive (VAR) techniques. Results, using daily prices over the 1980-85 period, suggested that fabricated cut prices and cattle prices are related to the imputed carcass value, carcass quote, and fed cattle prices. In addition, three fabricated cuts dominate as leading indicators of fed cattle prices of most fabricated cut prices. They are strip loin and bottom and top round prices. VAR models outperform the univariate and random-walk models of forecasting ability. |

| Forecast users and market analysts need quality forecast information to improve their decision-making abilities. When more than one forecast is available, the analyst can improve forecast accuracy by using a composite forecast. One of several approaches to forming composite forecasts is a Bayesian approach using matrix beta priors. This paper explains the matrix beta approach and applies it to three individual forecasts of U.S. hog prices. The Bayesian composite forecast is evaluated relative to composites made from simple averages, restricted least squares, and an adaptive weighting technique. |
